[ Oh. Oh. Oh. Hm. Zhongli is silent as Byleth asks that. Fantasies aren't something he's really thought about? Or better yet they're not something he's ever considered. He's simply done and had sex as naturally as possible here.

Humans and their ever-changing whims and fancies were things he was still trying to wrap his head around. His arms fold over his chest as he looks deep in thought. ]

I have...not considered such things before. But that is a common denominator for sex, isn't it? To live out one's fantasies with their partner.
